博客讨论了在使用Ajax进行数据请求时遇到返回值为undefined的问题。内容提到，当接口返回数据但控制台显示data.msg为undefined时，可能的原因和解决方法是通过eval()函数将返回的数据转换为JSON对象。

接口返回如：

{"msg":"success","data":[{"id":"1","company_id":"1","company_name":"网易","type":"1","dictdata_value":"访问地址","name":"system1.1_测试","url":"https://www.baidu.com/","status":"1","statusvalue":"有效"},{"id":"2","company_id":"2","company_name":"百度","type":"1","dictdata_value":"项目地址","name":"system1.1_生产","url":"https://www.163.com/","status":"1","statusvalue":"正常"},{"id":"3","company_id":"1","company_name":"网易","type":"1","dictdata_value":"访问地址","name":"system1.1_测试","url":"https://www.QQ.com/","status":"2","statusvalue":"无效"}]}

$.ajax({
               type: "GET",
               url: "http://localhost:8080/TTP/servlet/ProjectUrlList",
               data: "uid=fasdfasdfasdf",
               success: function(data){	
					$("#myDiv").html('<h2>'+data.msg+'</h2>');
                        
                  }
            	});

控制台无报错。data.msg 得到结果undefined。

eval()函数对返回的数据转换为json对象，即可解决
